A geographic object recognition unit () recognizes, using image data () obtained by photographing in a measurement region where a geographic object exists, a type of the geographic object from an image that the image data () represents. A position specification unit () specifies, using three-dimensional point cloud data () indicating a three-dimensional coordinate value of each of a plurality of points in the measurement region, a position of the geographic object.

Geographic object detection apparatus and geographic object detection method

A parallel processing starting unitthat partitions an inputted image into tiles each having a predetermined size, and distributes tiles obtained through the partitioning, and N tile encoding units-to-N each of that carries out a prediction difference encoding process on a tile distributed thereto by the parallel processing starting unitto generate a local decoded image are disposed, and each of N tile loop filter units-to-N determines a filter per tile suitable for a filtering process on the local decoded image generated by the corresponding one of the tile encoding units-to-N, and carries out the filtering process on the local decoded image by using the filter.

Video decoding device and video decoding method

Since time hierarchically encoded video data needs to include video data of a basic hierarchical layer, and video data cannot be generated in which a frame belonging to an upper hierarchical layer is only encoded, even in a case in which only a part of frames is processed, a basic hierarchical layer frame is needed to be included, and thus, there has been a problem that video data in which only the frame belonging to the upper hierarchical layer is encoded cannot be separately processed. In the present invention, a variable length encoding unit is disposed which encodes, for each sequence, a basic hierarchical layer existence flag showing whether or not a basic hierarchical layer is included in the sequence.

Optimized image decoding device and method for a predictive encoded bit stream

When an encoding mode corresponding to one of blocks to be encoded into which an image is divided by a block dividing partis an inter encoding mode which is a direct mode, a motion-compensated prediction partselects a motion vector suitable for generation of a prediction image from one or more selectable motion vectors and also carries out a motion-compensated prediction process on the block to be encoded to generate a prediction image by using the motion vector, and outputs index information showing the motion vector to a variable length encoding part, and the variable length encoding unitvariable-length-encodes the index information.
